So, finally got time for the Dyno last week, I know a few of you been waiting for my results... :-[


But,
Had to split engine (oil galley plug ???) this spring for the first time , took a while...
Lots of testing ign curves w butt dyno, think it`s no 35 now.... ::)
Bought a 907IE that was my new love during summer.
My two friends w a 750 & a 900SS w Mikuni CV carbs I wanted to have as references haven`t left their garage all summer! :mad:


Anyway, enough excuses:

Ignition used is an Ignitech TCI-P4 programmable unit. Read all here and you could also download
the software and have a look att all features: http://www.ignitech.cz/english/aindex.htm
Go to products, then TCI-P4.

What you do is:
1. Choose engine/ignition type (Cagiva 750)
2. Set rev limiter ( I choose 9,5k )
3. Set base advance ( go w default 10 )
4. Program a curve of your choice, at ten points you choose RPM & preadvance degrees.
DONE! Well, it takes some testing....duuh


Hard facts (my other engine mods, see below):

After adjusting A/F, I switched to OEM ign modules on the Dyno.
Where difference was largest, 5200 RPM, new ign gave + 3,5 Hp & + 6,5 Nm!
From 3700-6700 2Hp & 3Nm or more all the way.

If I use the same correction factor Ducati seems to use when they went from 84 Hp at rear to 95 at crank, 13%, I got at crank (comparison w a -07 Monster 1kDS, factory specs):
91,2 Hp/7200 RPM (95/8000) and 100,3 Nm/5500 (94/6k). SAE numbers. Sorry, broken camera &
no scanner so no chart.
According to the very experienced tuner, no signs of pinging on standard 95 oktan gas.

I`m very happy w the results! ;D 8) [thumbsup]
It`s so fun in the twisties, kept up quite good w a Mille R Factory, 749S & a M S4R yesterday.


Some more +:

1. Cost: 100 Eu! And replaces both OEM modules.
2. Instant start.
3. Engine feels like it has gotten a huge vitamin shoot.
4. Snakebite throttleresponse, as good or better as a well tuned ie bike.
5. So torquey in 5/6th gear. Lurking in 6th at 60mph, then passing is a breeze & most addictive.
6. Very smooth low revs/small throttle openings. Responds from 2k in 4th w/o rattling to pieces.
Less aggressive advance in this RPM range and you`ll get this overall smoothness.
7. Aggresive sound! Sounds like something is happening down there... >:D
8. Stuff is supplied to make an extension cable to place the unit at your own choice.


Any cons? Well the Czechs are not so responsive w mail. But you`ll get one.
Still have a question why I had to have 400 Ohm resistance in parallell over ign pulse from motor, no answer from manufacturer/distributor. Too strong pickup signal was disturbing idle.
Tried to understand base advance and get that right but it doesn`t seem to matter, default 10 degrees seems good.


I`ll be happy to answer any questions!
(And I have no stocks or economical interest in this company... ;))

That`s funny, I downloaded software again just now and started it w/o any problems.
Maybe try it on another PC? Think it works from OS W95(!) and on.

Yes, you just mail them. They can be slow w answers. Payment via bankers draft
here in Europe anyway.

Software ran fine for me, but there was no choice for Cagiva.

My mistake.
You choose Classic ( 1 lobe, 1 or 2 pickup) on Motorbike type on Bike tab.
The default map I got is for a Cagiva 750 Elephant he told me.

What's that email friend? This is just what I've been waiting for - I'll start the ball rolling with an order for 3.

Yes, it is cool. 8)
Module is bolt on, 20 second switch, no wiring needed!
See my engine mods in my profile below in my posts.

downloaded it again and it works fine. tps voltage has the same orientation as a map sensor too, so you could use a map sensor to give extra part throttle advance.

i'll email him from work tomorrow to see about getting one.

maybe the base timing thing is an offset to allow for where the pickups sit and what timing they give as fitted. perhaps.

this unit is exactly what i wanted to get made, and i was going to use an offset of some sort to allow the timing specified to be aligned with the pickup position, without having to pull the side cover off and reset the pickups.

Great!
Finally I can get Brad back some useful stuff for all the hard earned info he shared w us! ;D 8)


From what I have understood of base timing, it`s the preignition engine needs at idle/no load.
You calculate it via the total length of of the outer radius of the flywheel, compared to the two ignitition points on the flywheel. If wheel is f e 475mm total & 1 turn is 360 degrees, 1 degree is 1,32mm. Distance between the 2 ign points on my flywheel is 38,5mm. 38,5mm equals 29,5 degrees.
Max advace is supposed to be 38 degrees = base advance should be 9 degrees. Am I right (I`ve had a few beers tonight...)?


Anyway, you could adjust the ignition curve and the base advance totally independent w this unit!

As mentioned before, the Czechs could be slow w answering mail.


without having to pull the side cover off and reset the pickups.
Which affects the whole ignition map,w this unit you don`t have to do that.
But it sort of can do that, it has a +/- feature for the whole map except base advance.


And btw, I haven`t used the TPS just to make things less complicated, amateur as I am... ::)

i've been logging my 750 with a map sensor on it for manifold vacuum. cruising at 60km/h it's running about 18 cm vacuum, or 3.5v. at 110km/h it's running about 14 cm vacuum, or 3.7v. you could easily equate that to a tps % (min 0v, max 4.85v) and just use as required. should help pick up fuel economy.

group buy sounds ok, but they'd need to go to a few different places - i'm in aust. and they give 25% off if you buy 10 or more - that's not going to attract many importers or dealers i wouldn't think. we'd need to get a fair few connectors too - you could just plug straight into the loom that way.

you could set the timing to 10 degreees over the whole range and check it with a light to see the offset anyway. i'm sure they've thought of it. maybe i should just read the instructions.

when can i get it, when can i get it, when can i get it, when can i get it, when can i get it, etc. [laugh] ::)

one of the big issues i've had with the 750 (minnie the 600m w/750 motor) is the spot just before the advance starts (1500 to 2,000), especially on cold mornings as i go straight into lane splitting at the end of my street. i've now gone to 42.5 pilots, but like that it's a bit rich at 50 or so km/h cruise. with this the progressive advance should eliminate a lot of that issue and the need for overly rich mixture just there. so i can go back to 40 pilots, which are better for fuel economy.

page 5 of the instructions shows the base advance as the degrees between the trailing edge of the lump and tdc. so it should be a nominal 6 degrees in the case on non adjusted pick ups on a carb ducati 2v. you can adjust the first step down to 200rpm, so you'd use this for idle and below. i guess if you wanted advance to start at 1300 rpm then you'd make that lowest point 1300 and it would be fixed under that and vary up to the next point from there.

can't wait to try it.

Tried both one and two points for idle under 1000RPM, no work for me.
Mine actually best w 1st point 1500/6 degrees, 10 base adv.
Tried 0,8,9 base adv, didn`t really notice any difference?!?

2000/14 makes it smoooth low revs/small throttle openings.

Measuring full advance w strobe on flywheel could be up to 1,5 degree wrong.

Can`t wait to see what a pro can do w this! ;)

When ordering you must stress that you get connectors. One of us here in Sweden didn`t get them,
two others, incl me, got them + ones to make an extension.

If you put together a group buy, I want 3, maybe four, and I'm a shop if that might help. I DEFINATLY need connectors, a few extra if possible.
Who wants to run point on the group buy effort? Jeff H. might want a few for the DML store.

Norm,

I'm thinking this might be a great thing for that motor you're building me.

A buy of 10 units will reduce the price quite a bit.
Yuo must stress that you get the connections.
And, again, they can be slow w replys.
But last week they`ve responded to me in a day or two. :)
